Has anyone succeeded in modifying the code to make use of the TTL USART2 port? I have a USART compatible sensor, but am just beginning to learn C and the Microchip 18F8520.
I miss the days of just hooking up a pot or analog sensor (gyro) and being able to read the value of a byte directly. Mechanical engineers get spooked around all this programming/computer science stuff.
Your help is appreciated.

Yes, i have some experience with the USARTs. What kind of sensors are you using?
If u need some code i can do that. I can give you some code i wrote to read
these sensors.
